GST debate not over, Cormann tells Barnett

THE West Australian premier's claim the state has "won the argument" about sharing GST revenue has been rejected by Finance Minister Mathias Cormann, who says the debate has a fair way to go.

COLIN Barnett made the comment after reported ructions at a joint party room meeting this week, when Treasurer Joe Hockey took aim at WA's budget management after member for Pearce Christian Porter complained the state was not getting its fair share of GST.
